Definitions

  • the object is achieved by a laser processing machine for joining two workpieces, in particular of a hardenable steel, with a laser processing head and with workpiece holders for the workpieces, which has means for relative movement of the workpieces for generating a usable for preheating the joining surfaces frictional heat.
